Antithrombin III or AT 3

1. Antithrombin III has two types: Inherited and Acquired

The inherited antithrombin deficiency has a higher risk for blood clots in the body since it is due to a genetic abnormality. It has two categories: Type I which is described as a decrease in antithrombin activity and its concentration in the blood of the affected individual and Type II which is the normal level of antithrombin in the body but a decrease of its activity in the blood of the affected individual.

The acquired antithrombin deficiency is associated with underlying disorders in the individual such as liver and kidney diseases, cardiac surgeries, a protein losing condition, etc. It can be a result of treatment for certain type of blood disorders.
